Application filed June 7,

To (ZZZ whom it may concern.-

Be it known that 1, JOHN J. Cesar, a citizen of the United States,residing at Gloucester, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inStrainers for Gasoline, of which the following is a specification,reference being had therein to the accompanying drawing.

My invention relates to strainers, and has special reference to suchstrainers as are used on gasoline lines and the like. It has for itsobject the production of an improved device of this class which will notclog, which may be used ineither a horizontal or a vertical position,and which may be easily taken apart and the strainers removed forcleansing or other purposes. Other objects will appear from the detaileddescription and claims hereinafter.

I attain my objects by mounting a plurality of cup shaped strainers ofdifferent meshes, in a cage supported in a casing which it divides intoapproximately equal chambers, one for intake of liquid and sediment andthe other for clean gasoline. The coarsest mesh is on the intake side,and means are provided for removing sediment and for blowing or washingout the entire casing and strainers when desired without taking thecasing apart.

My invention is illustrated in the accompanying drawing in which:

Figure 1 is a side view of the device complete.

Figure 2 is an end view.

Figure 3 is a section thereof on the line 33 of Figure 2.

Figure i is a side View showing the cage and strainers removed from thecasing.

Referring to the drawings, 1 is a metal casing comprising a tubular bodyfitted with end caps 2 and 3, having central tapped openings closed byscrew plugs 2 and 3, and lateral nipples 2 and 3 for connection todischarge, and inlet'pipes or tubing, respectively. In the side walls ofthe body are lugs 4; projecting inwardly to receive and hold the cagewhich carries the strainers 7 and S. The cage is in two parts, one partcomprising a flanged ring or body 5 with arms 5 supporting a lower ring5" for protecting the lower strainer; and the other part comprising aclamping ring 6 threaded into the flanged cage ring 5, and

carrying a bent up cross bar 6 which serves to protect the upperstrainer and also for engagement of fingers or a wrench to turn theclamping ring 6.

The two strainers 7 and 8 are cup shaped with flanged edges, the flangeslying as shown upon the flange of the body ring 5, and being clampedthereto by ring 6. Interposed spring washers may be employed if desired.The lower strainer 8 is of coarse mesh and the upper strainer 7 is ofvery fine mesh screening.

in operation the liquid to be strained, as gasoline, passes in throughnipple 3 as indicated by the arrow in Figure 3, thence upwardly throughthe coarse strainer 8 and the fine mesh strainer 7, into the upperchamber and so out through nipple 2 This strainercannot become clogged,any matter that would ordinarily have that action bein stopped at theloweror coarse mesh member 8, and the gasoline in the upper chamberbeing perfectly void of any dirt or sediment; The device as a whole maybe connected completely to a gasoline line, either pipe or coppertubing, in a very short time, and will operate with its axis eitherhorizontal or vertical. In either case gravity assists in keeping thescreen 8 clear of sediment, which may be drawn off through the loweropening in casing 1 by removing plug 3 or may be blown out thoroughly byremoving both plugs.

I am aware that various changes and modifications may be made in thisdevice without departing from the spirit of my invention. For example,the strainers may be held in the cage by a groove in the inner face ofthering 6 and a spring ring or washer therein. Various other changeswill. occur to those skilled in the art, and I wish it distinctlyunderstood that I contemplate all such changes as fall fairly within thescope of the appended claims.

I claim:

1; A strainer for liquid supply lines comprising a cylindrical casing orbody, bearing lugs therein projecting inwardly, an upper and a lower endcap fitted to the body, each having a centraltapped opening closed by aremovable plug, and each having a lateral nipple for connection todischarge and to inlet pipe or tubing, respectively, and a cagecentrally disposed in said body and supported on said lugs, said cageenclosing a pair of strainers and beingi in two parts,'one'partcomprising afianged ring or body with arms supporting a lower ring forprotecting the lower strainer,.and the other part compris- 5 ing aclamping :ring threaded into the flanged ring of the'first part so as toclamp the strainers between them, and carrying a bent up cross barserving to protect the upper strainer and also to turn the clampingring.

"2. A strainer as claimed inclaim 1 in which the strain-i-ngelementswithin the cage are in the Y form of flanged cups with their flanged.edges placed together: and clamped between the two parts or the cage.

'3. A strainer-as claimed in claim 1 in whichthe-strainingelementswithin the cage are in 'the f orm o'l fianged oups with their flanged:edges placed together. :and clamped betWeen the two partsof the cage-andin which the said twocup shaped straining elements are ofdifierentamesh;the-coarser mesh zbeing enithe inlet side.

4. A str iilGlffOlI liquid supply lines com- 2 prising a hollowcylindrical casing or body,
